Abstract
Substantial loss of water though percolation which reduces the crop water productivity in flooded rice cultivation. Sustainable agricultural practices that can lead to higher productivity, optimum use of capital labor, less input cost and less requirement of water. There are several strategies to bridge the yield gaps and the system of rice intensification (SRI) is one of the promising approaches for achieving sustainable rice production and increasing food security of small-scale producers. SRI, significantly harmonizes the elements of soil, water, light and plant, it allowed the plants to achieve their fullest potential. SRI is found to be an integrated agro -ecologically sound approach to irrigated rice. It is also a designer novelty that competently uses scarce resources. SRI was found to benefit farmers more in terms of more income with less input, given higher yield with lower investment and beneficial to poorer households. Yield was also found to be higher in SRI with 8t ha-1 as against 3 t ha-1 under conventional paddy. Along with better nutrient uptake also maintains soil health sustainably. Therefore, the system of rice intensification is the best option for rice production in order to meet up with the demand of the increasing population along with mitigating green house gases (GHGs) production from rice fields. In this paper, significance system of rice intensification on rice productivity, plant and soil nutrition has been reviewed and discussed.
